Lagless vsync after winuae 3.61 isnt buttery smooth

[Mixter]

Hello

I have discovered that on my nvidia gtx 570/i7 2700k computer setup with 1920x1080 , after version 3.61 (4.00 and up) 64 bit and 32 bit lagless (beamraced) vs doesnt work smoothly in rtg/native.

Buttery smooth on 3.61 both on rtg/native (low latency vsync used instead)

I have tested all versions above 3.61 (4.00 to 4.4) and its same problem.

I also tested with new configuration, no avail

Is my computer too slow to handle newer winuae versions?
It works great with another Whdload config with 3.1 ks - on 4.00 and above (no rtg and jit)

Maybe its something other problem that I have to search for, maybe MCP on the other non-whdload configuration? old uaegfx? etc
I have tried changing no rtg and jit on the non-whdload config, no difference

Maybe there is a compability mode for newer than 3.61 display code?
In RTG the cursor is so slow 5 fps etc.. AMOSPro slow 10 fps
3.61 100% smooth 60 fps no tearing etc

If I select "-" on all display settings for vsync its smooth but tearing

I also tested with amiga early startup control, it was not smooth either so it could be something with the configuration as the WHDload config was smooth

I loaded the WHDload config and changed harddrive, the result is Native mode is smooth in lagless but not in rtg mode.
I changed from native cpu speed to fastest, its not smooth on both RTG and Native

The search continues...
Is my GFX card too old ? EDIT: I found a difference of CPU usage 14% in 4.40 up to 18% in 3.61 in AMOSPro game code interpreter execution ... hmm no idea

Removed all configs, created new, no difference. I think must be the graphics driver is too old for old GTX 570 and also Win10 updated to 2004...
Toni, it would be really nice to have back "compatibility lagless vsync" as in 3.6.1 in winuae 4.5... for old graphics drivers that maybe give wrong values

Alternative is maybe to buy new graphics card like a used GTX 1060 (searching now) 100 usd

I bought new GFX card a GTX 1060 3gb... doesn't help.
Can try a new installation of windows 10 on another HDD maybe...

EDIT: I have suceeded, I think it is a configuration issue, I have managed to achieve smooth on 4.4 winuae but using other configuration
But it is always P96 that is smooth, not native and vice versa. Strange...

Tried to change into DX9 and DX11... DX11 was worse

Lets start from basics first. Does same happen in standard a500 config? (Fast CPU or RTG means too many unknown variables)

Also, did you try turning the number of slices (the numeric drop-down menu to the right of the vsync selection when a beamraced mode is selected) down to 1?

[Mixter]

Yes, I tested with Turrican 3 and a500 config, floppy etc. PAL filter, bilinear, Full-window
Lagless vsync (beamraced) 1 slice works perfectly.
So this is not a driver problem
